Abstract A liquid discharge nozzle for discharging liquid generally upwardly therefrom has an elongate straight body which defines a duct which extends between liquid inlet and outlet openings at the lower and upper ends of the body. A plug having substantial length between its opposite ends is disposed across the duct adjacent the duct outlet opening. A plurality of liquid flow passages are defined through the plug at regular intervals around the plug at locations proximate to the periphery of the plug. An elongate cylindrical liquid flow director member extends from the plug lower end along the duct toward the lower open end of the body. The director member and the body cooperate to define an elongate annular liquid flow path between the passages and the liquid inlet opening. The annular flow path gas a width transversely has the body which is sufficiently great to prevent the upper end of the director member from restricting to any significant degree the liquid flow area of the passages formed through the plug. The director member has a length which is substantially greater than any dimension of the director member transversely of the duct.

A liquid discharge nozzle for discharging liquid generally upwardly therefrom comprising a. an elongate straight body defining a duct therethrough between a lower liquid inlet opening defined at an open lower end of the body and an upper liquid outlet opening defined across an open upper end of the body; b. a plug having substantial length between opposite ends thereof relative to the diameter of the duct disposed across the duct adjacent the duct outlet opening; c. a plurality of liquid flow passages defined through the plug at regular intervals around the plug at locations proximate the periphery of the plug and at substantially uniform distances from the periphery of the plug, the passages communicating between the duct and the exterior of the nozzle; and d. an elongate liquid flow director member extending from the plug along the duct toward the liquid inlet opening, the director member being of cylindrical configuration for at least a substantial portion of its length immediately adjacent the plug, the director member and the body cooperating to define an elongate annular liquid flow path extending from the passages toward the liquid inlet opening, the director member at its upper end having a diameter substantially identical to the diameter of an imaginary circle defined on the lower end of the plug by the low side of those points on the bottom openings of the passage lying farthest from the periphery of the plug, the director member having a length along the duct which is substantially greater than any dimension of the director member transversely of the duct.
